Application filed February 8, 1915. Serial No. 6,785.

To all whom it may concern:

Be it known that we, ALFRED STELL and J OHN STELL, subjects of the King of Great Britain, and residents, respectively, of Greenhill, Steeton, nearKeighley, in the county of York, England, and 30 Devonshire street, Keighley aforesaid, have invented a certain new and useful Improvement in Dofling Apparatus for Spinning and like Machines, of which the following description, together with the accompanying sheets of drawings, is a specification.

Our invention relates to improvements in dotting. apparatus for spinning and like machines of the class known as flier frames. and consists in improvements in the construction and arrangement of certain parts forming said apparatus whereby the functions of doiiing are facilitated by the means for moving the spindles and bobbins, the parts carrying same being more easily manipulated than heretofore, while the devices for moving and cutting the threads are mounted in more convenient positions- In order that our said invention may be readily understood, we have hereunto appended sheets of drawings illustrative thereof, to which, by figures and letters, reference is made in the following description:-

Figure 1 is an end elevation showing the application of our improved devices to a machine for spinning flax, jute or the like.

Fig. 2 is a front elevation of said machine.

Fig. 3 is a sectional end elevation of a portion of said machine showing the different parts in. the positions they occupy during spinning operations.

Fig. i is a similar View to Fig. 3, but shows the spindles canted ready for the doifing operations to be performed, the bobbins being supported on the spindles by the dagger pin devices hereinafter described.

Fig. 5 is also an end elevation of certain parts shown by Figs. 3 and 4t and illustrates the different parts in the positions they occupy when the full bobbins have been deposited upon the pegs arranged for the1r reception, the empty bobbins moved lnto alinement with the spindles, and with parts.

in position ready for raising said bobbins Fig. 8 is plan of two spindles and the pegs operating in connection therewith, showing both of said pegs opposite to or in alinement with said spindles.

Figs. 1 and 2 are drawn to a smaller scale than the remainder of the figures.

Similar letters and figures of reference indicate like parts throughout the several views.

The annexed drawings illustrate the application of our improved parts to frames or machines for spinning jute, flax, hemp or the like, but it will readily be understood therefrom and from the following description how our said improvements may be applied to ordinary worsted spinning or other machines.

A indicates the ordinary framework of the machine; B the fixed rail through which pass the rods for raising and lowering the lifter plate C and the racks for raising and lowering the rail D carrying the foot steps for spindles 1, which latter are supported from the oscillating bar E in manner hereinafter described.

The lifter plate 0 supports the bobbins when in the spinning position as indicated by Figs. 1, 2 and 3, and raises and lowers said bobbins 2 within the fliers 1 to regulate the building of the yarns on said bob bins by the uide eyes 3 in manner well'understood. he reciprocating of the plate C may be effected in any well known manner but in the machine illustrated it is operated from the shaft- 5 of the lower rollers 6 through the pinion 7, gear wheel 8, pinion 9, wheel 10 the shaft 11 of the upper rollers 12, the pinion 13, gear wheel 14 (which is mounted upon the same shaft or stud 115 as the cam 16) which latter operates the lever 17 (fulcrumed at 18 and provided with an antifriction bowl 19) a connecting rod 20 reaching therefrom into connection with a chain 21 which passes around the chain pulley 22 .mounted loosely upon the shaft 23; which latter has fixed upon it=the hand wheel 2%. The pulley 22 and wheel 2 1-are connected together by the spring-controlled ,pin 25. Fixed upon the shaft 23 are the chain pulleys 26 to which are fastened chains-2'6 connected by'the cross pieces 26 with the rods 27 carrying thelifter plate C. The connection between the chain pulley 22 and the hand wheel-2 1: enablesthe building of the yarn onthe bobbins to be cflected'in: the ordinary manner. automatically from the cam 16, while bydi'sengaging the pin 25 from said chainpulley 22, the shaft 23 may be rotated byhand so as to adjust the lifter plate-C as and whenever. desired, such aswhen itis necessary to effect the dofiing operations.

The fliers 3- are provided with whorls 28 fixed'upon them. The lower endsl. of the spindles 1 take within bushings 35 formed in p the movable rail D said bushings holding racks d3 carry-a plateor rail 46 upon'which the spindles -1 against lateral movement when the parts are inthe spinningposition as illustrated by Figs 1, 2 and The bar or rail D is raised and lowered by the racks 36 which are traversed by the pinion 37 fixed upon the shaft 38, this latter being provided with a handle 39 by which itis oscillated as desired. v

In appropriately arranged brackets 4L0 we mountashaft -11 having fixed upon it a series of pinions 42 thesepinions gearing with racks d3 sliding in the bearings 141- supported by the brackets 41-0. Extensions d5 from the are mounted plates or cross pieces e7 having fixed upon them pegs 428, 49. 01' instead of the cross pieces e7 we 7 may mount the pegs 18,- 49 upon t vo-plates or b'ars' lti fixed upon theracksl3 or upon extensions thereof (see Fig}. 5*) such bars extending the length:

of the frame. The pegs d8, 49" are arranged in. alinement with 0 opp-osite to the spindles 1, and are capable of bccupying'diiferent positions such as that wherein the pegs 48 are in. alinement with said spindlesl when same are intheir canted or inclined positionsas shown by'Fig-d, or that wherein the pegs 19 are in al-inementwith said spindles'as shown by Figs. 5 and'6. The pegs 4E8 -are for receiv-ingthe full'bobbins 2,- while those l9 are for receiving the empty'bobbins2 as" shown by said Fig. 5; the movement toward and from the framework'of-"theymachine to" cause thepegs48 and lt) to assume the positions. desired" being efiected' by rotating the inions;42;by;meansof. the handle 50 fixe .iiponthe' shaft {11. q p

' Arranged to slide 'inbearingsol areracks 52, the said bearings being so arranged upon the brackets TO that as said racks are raised by their pinions the upper ends thereof advance toward the framework A. The pinions 53 are fixed upon the shaft 5i which is rotated by the hand wheel At the upper ends of the racks 52 we hinge at 56 a bar 57 upon which is fixed a series of pegs or bifurcated pieces 56 these being for the purpose of moving the threads from the spindles 1 when the full bobbins 2 have been deposited upon the pegs d8. Attached to the bar 57 is a notched plate 59 around which takes a series of plates 60 attached to a bar 61, provided with a handle 62 and sliding within bearings 63 carried by certain of the racks 52. The bar 57 and all the parts carried upon the hinge 56 are capable of being turned o swivcled through any appropriate angle such. as an angle of ninety degrees or through a semicircle, in order that they may be moved into the position shown by Fig. l or by Fig. 3, or into the position illustrated by Figs. 5 and 6. where the pegs 58 are shown as in the desired position for sup porting the empty bobbins 2.

The bar E is carried by hinged bearings Gdavhich are supported by the brackets 65 fixed upon the cross bar F of the machine, the outer ends 66 of said brackets forming a support fo the lower end of the bar E when the parts are in the spinningposition shown by Fig. 3; Fixed beneath the bar E are arms 6701' quadrants 68 these latter gearing with other quadrants 69 fixed upon the shaft 70 which is operated by the handle 71. This handle? 1 is pressed or drawn into notches 72, 73 -formed on a bracket T-1- by the spring 74 these notches being so arranged that when said handle 71 rests within the notch 72 the spindles 1 are in their vertical positions as required during the spinning operations, or when in the notch 73 said spindlcs occupy their canted positions as during doliing operations.

A shaft or rod 75 is carried in brackets 76' by the quadrant 68 said shaft having fixed upon it arms or fingers 7 7 which actas steadiers for the spindles operations. Another bar or shaft 78 is carried by said quadrant 68 and has arms 79 fixed upon-it, these arms being provided with pins 80 which are for the purpose of entering the yarn on the full bobbins 2 as shown by Fig. 1, or of-taking below the up per flanges of the empty bobbins 2, as illustrated by Fig; 6. These steadying fingers'anddagger pins are both of them well known for the purposes which we employ them:

The dofiing operations as performed by our said improved parts are as follows nissuming that the *bobbins- 2 have received thedesircd quantityof yarn andjth'at 1 during dofliug dles 1 and substitute for them empty bobbins 2 the motions of the machine are arrested and the arms or the fliers 4: are moved into alinement with each other in the manner and for the purpose well known. The steadying fingers or arms 77 are then moved by the handle 81 so as to press against the spindles 1 and the dagger pins 80 are moved by the arms 7 9 (which are operated by the handle 82) so as to enter the yarns on the full bobbins 2. The rail D carrying the footsteps 35 for the spindles 1, and the lifte plate G are then lowered to positions where they are both clear of the lower ends 1 oi the spindles 1. The said spindles 1 are then moved by the handle 71 into the position in dicated by Figs. a, 5 and 6, where they are in alinement with the pegs 48 when same are in the position indicated by Fig. 3, on which the dagger pins 81 are moved away to release the full bobbins 2 which fall on to the pegs is beneath.

The rail 16 is then moved by the handle 50 to carry the pegs 48 away from the framework of the machine and the pegs 19 into alinement with the spindles 1. The bar 57 is then raised by the racks 52 and their operating parts into a position in proximity to the spindles 1 so that they may remove the threads from said spindles in manner well known, the bar 57 being oscillated for this purpose upon the hinged bar 56 by means of the handle 62, after which the said bar 57 is lowered and the fingers 58 turned intoposition so as to be passed beneath the flanges 2 of the empty bobbins 2 these being then raised by said racks 52 and fingers 58 over or along the spindles 1 to a position where the dagger pins or holders 80 may be passed beneath the flanges 2 on said bobbins as shown by Fig. 6. The quadrants 68, 69, are then operated by the handle 71 to carry the spindles 1 back into their vertical positions as shown by Fig. 3, the lifter rail 0 and the rail D being then raised into their normal positions over said spindles 1. The bobbins are then allowed to fall on to the litter plate C by withdrawing the dagger pins 80 and steadying pins 7.

The bar 57 carrying the thread cutting device is then raised so as to catch the threads extending from the full bobbins 2 to the empty bobbins 2. A few turns are then given to the bobbins after which the threads are severed in manner well known. The several parts are then returned to their normal positions whenthe spinning operations may be re-commenced.

From the foregoing description it will be seen that by the employment of a peg rail which is movable toward and from the spindles as hereinbefore described, very little useful space in front of the spindles is occupied during spinning operations, the

mounting and operatingof the racks carrying the thread cutting and moving devices also being conveniently arranged for this purpose, while the spindles 1 are only required to occupy two positions, one in the vertical spinning position and the other canted so as to be in alinement with the pegs 41-8 or the pegs a9 as hereinbefore described.

Such being the nature and object of our invention, what we claim is 1. In a spinning or like machine, a series of spindles supported at their upper ends, means for canting said spindles, a series of bobbin. receivers simultaneously movable into position to receive filled bobbins from said spindles, a series or" bobbin carriers simultaneously movable into position to supply empty bobbins to said spindles, means for moving said bobbin carriers and said bobbin receivers simultaneously andrespectively into and out of positions in alinement with the canted spindles, and means for moving the empty bobbins simultaneously from said bobbin carriers on to said spindles.
